Dry Eye Q&A

Frequently Asked Questions

QWhat are effective treatments for dry eye?

A wide variety of dry eye treatments are available depending on the patient's symptoms and condition.
In general, mild cases of dry eye are treated using eye drops that help retain moisture, eye drops containing moisturizing ingredients, and other formulations to replenish tears that have decreased. It is very important to improve the quality an quantity of tears in the treatment, and eye drops can often help. However, if dry eye cannot be managed with eye drops, treatments may be given to suppress the outflow of tears by artificially closing the lacrimal punctum, the outlet of tears.
If you are worried about your symptoms, it is important that you see an ophthalmologist so that the severity of your dry eye and the best treatment for your dry eye can be determined.

QWhat is the treatment for artificially closing the tear outlet to keep tears on the eye surface?

This treatment is known as punctal plugging, in which the outflow of tears is suppressed by closing the lacrimal punctum, the outlet of tears, causing tears to accumulate on the eye surface.
This treatment can be performed via two methods, by inserting a tiny silicone plug to the upper and lower lacrimal puncta, and by suturing each lacrimal punctum (known as punctal closure surgery).
This treatment is generally used to treat relatively severe cases of dry eye, and is not applicable to all patients. Atelocollagen plugs that can be used for relatively mild dry eye have recently been developed.

QMy eyes are dry because I use personal computers all day long. Are there any good preventive measures?

The following measures are available:
Preventive measures you can implement while using a computers include:

  • Blinking your eyes intentionally
  • Using a humidifier to add moisture to dry indoor air
  • Positioning your computer screen below eye level
  • Sitting in a position where the flow of air from air conditioners do not blow directly into your eyes
  • Taking adequate eye breaks

If we continue to look at a television or computer screen (gazing), our blinking frequency decreases to nearly 1/3 to 1/4 of the normal level, or about 20 to 30 blinks per minute, which in turn can dry and injure the pupil surface (cornea). The number of people with this type of dry eye has recently increased. If you have severe symptoms, such as eye strain and a sandy feeling in the eye, or if you do not feel relief from your symptoms even after a sufficient eye break, it is a red signal for dry eye. You are encouraged to consult an ophthalmologist who can check your eyes for injuries.

QIf my eyes are dry, What type of contact lenses should I use, hard or soft?

Consult an ophthalmologist and choose the type that fits you.
Dry eye in wearers of contact lenses may be caused by a wide variety of factors, including the material, size, and fitting of the contact lens. Among the many types of contact lenses there are soft contact lenses that are made using a polymeric substance that has high moisture retention, which is expected to lessen the sensation of dryness. Schedule a check-up with an ophthalmologist and have suitable contact lenses prescribed for your condition.

QAm I likely to experience dryness of the eyes when wearing contact lenses?

The use of contact lenses is considered to be closely associated with dry eye.
About 80% of soft contact lens wearers and about 70% of hard contact lens wearers complain of dryness of the eyes. Tears serve as a lubricant between the contact lens and the pupil (cornea) to protect your eyes. In a state where there is a decrease in tears, the cornea and conjunctiva are likely to be injured, which in turn can reduce their resistance to bacteria and cause severe corneal infections. In addition to the proper maintenance of your contact lenses, be sure to undergo periodical check-ups with an ophthalmologist.

QCan dry eye be cured?

At present, no treatments are available to eliminate all causes of dry eye.
Mild and severe symptoms are treated in considerably different ways because dry eye is caused by a wide variety of factors.
You are encouraged to consult an ophthalmologist who can help you decide the proper treatment for your symptoms.

QIf dry eye are left untreated, what happens?

Subjective symptoms, such as dryness or a sandy feeling in the eye, as well as eye surface disorders (injuries) may worsen.
In addition, bacteria may enter the eye via the injuries and cause severe corneal infections. If people with these conditions wear contact lenses, their symptoms may worsen.
If you experience these conditions, don't leave the symptoms untreated and consult an ophthalmologist.

QIs there a relationship between age and dry eye?

The volume of tears secreted decreases with age because the secretory function of the lacrimal gland, which produces tears, decreases.
Decreased tear secretion is considered to be one of the causes of dry eye.
On the other hand, the function of tear drainage (lacrimal drainage) may sometimes decrease, resulting in a decreased volume of tears flowing out. This means that dry eye do not always occur with aging.

QI have been using an eye drop formulation I bought at a pharmacy. Is there an issue with continuous use?

If the eye drop formulation you bought at the pharmacy does not relieve your symptoms, consult an ophthalmologist.
While tears play a role in delivering oxygen and nutrients to the pupil (cornea) and in killing bacteria that have entered the eye, too frequent instillation of eye drops may cause valuable tears to be washed away.
In addition, patients with dry eye may have their eyes injured by the influence of ingredients in their eye drops because the ingredients are not diluted by their tears. If you do not experience relief from your symptoms, consult an ophthalmologist.

QIf my rating on the Check Dry Eye! scale is “Your risk of having dry eye is at MAXIMUM, then am I affected by dry eye?

Yes, it is ‘likely that you have dry eye.’
Even if your rating on the ‘Check Dry Eye!’ scale applies to some symptoms, it does not mean more than you ‘likely have dry eye.’ In addition, you may have a disease other than dry eye. If you experience several problematic subjective symptoms, don't leave these symptoms untreated and see an ophthalmologist to undergo an expert examination.
